Patented July 25, 1939 UNITED STATES PATENT oEEleE 2 Claims.

The present invention relates to new and useful improvements in grease containers and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character 5 embodying a novel construction, combination and arrangement of parts through the medium of which the lubricant orother material therein may be conveniently dispensed in any desired quantities'for filling guns, etc.

Another very important object of the invention is to provide a grease container of the aforementioned character in which the lubricant may be shipped.

2 Still another important object of the inventionis to provide a grease dispensing container of the character set forth embodying an ejector in the'form'of a piston including novel means whereby said ejector may be inserted in a full container from the-top thereof.

Other objects of the invention are to provide a grease dispensing container of the character described which will be comparatively simple in construction, strong, durable, highly eflicient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and. advantages of the invention will become'apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a perspective view of an embodiment of the invention.

Figure 2 is a View in horizontal section through the device.

Figure 3 is a vertical sectional View.

Figure 4 is a fragmentary view in vertical section through an upper portion of the device, showing the connection for the removable discharge spout.

Figure 5 is a perspective View of the grease ejector.

Figure 6 is a fragmentary View in vertical section through a portion of the ejector, taken substantially on the line 66 of Fig. 5.

Figure '7 is a view substantially similar to Fig. 6 but showing the check valve in open position.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a container which is designated generally by the reference numeral I, said container being of any suitable .material, preferably metal, and including what may be referred to as a cylinder 2 for the reception of the lubricant, as at 3. The container I further includes a bottom 4 in the lower end portion of the cylinder 2, said bottom having a vent 5 therein. The container I still further includes a top 6 of the sunken type which is removably mounted in the upper end portion of the cylinder 2.

Extending rotatably through a centrally located opening which is provided therefor in the top 6 to a point adjacent the bottom 4 of the container I is a vertical screw shaft I. Threadedly mounted on the screw shaft I for vertical movement in the container I beneath the lubricant 3 is an ejector 8. The periphery of the ejector 8 has formed-therein a groove or channel for the reception of a ring 9 of suitable material, said ring being substantially square in cross section, as illustratedto advantage in Fig. 3 of the drawings.

The screw shaft I extends above the sunken top 6 of the container I and secured thereon by a pin III is a sleeve II having an external flange I2 on its lower end. A packing washer I3 is provided between the flange I2 and the top 6 of the container I for preventing leakage around the screw shaft I. Journalled for swinging movement on the end portions of the pin I9 is a handle I4 of the loop type.

The reference numeral I5 designates a neck which rises from the top 6 of the container I. As shown to advantage in Fig. 4 of the drawings, the neck I5 includes an inturned flange I6 on its upper end. Removably mounted on the neck I5 is a discharge spout I1. The spout I! is provided with an external flange I8 on its inner end. The spout I1 is removably secured in position through the medium of a coupling I9 which is threaded on the neck I5 and which is provided with an internal flange 20 on its upper end engaged over the flange I8. A packing 2| is interposed between the flanges I6 and I8 to assure a leak proof joint.

It is thought that the manner in which the device functions will be readily apparent from a consideration of the foregoing. With the ejector 8 in the bottom of the container I on the lower end portion of the screw shaft I, said container is filled with the lubricant. The spout I7 is removed and the neck I5 may be closed in any suitable manner for shipment. During shipment, the handle I4 is swung downwardly to an out-of-theway position on the top 6 of the container. When it is desired to dispense the lubricant the spout II is attached and then, by rotating the shaft I in the proper direction through the medium of the handle I4, the ejector 8 is elevated in the cylinder 2 in a manner to force the lubricant from the contained through the spout.

If desired, the screw shaft 1 with the ejector 8 thereon may be inserted in a full container of grease. To permit this, the ejector 8 has formed therein openings 22. Projecting inwardly from the lower portions of the walls of the openings 22 are flanges 23 constituting seats. The reference numeral 24 designates check valves in the form of plates which are loosely mounted for swinging movement on the ejector 8 and engageable with the seats 23 for closing the openings 22. The valves 24 swing loosely on headed retaining pins 25 which are mounted on the seats 23 in the openings 22. Angular extensions 26 are provided on the pivoted ends of the valves 24 for engagement with the seat 23 for limiting the swinging movement of said valves toward open position. This is shown to advantage in Fig. 7 of the drawings. Thus, when the ejector 8 is forced downwardly through the grease in the container, said grease passes upwardly through the openings 22, swinging the check valves 24 to open position. When the ejector 8 is moved upwardly by the screw shaft l for ejecting the grease the valves 24 close on the seats 23. The construction and arrangement is such that the elements 25 and the valves 2 when in closed position, do not protrude above the upper surface of the ejector 3. Of course, when the ejector 8 is installed in this manner the bottom i of the container I must be rendered leak proof by closing the vent in any suitable manner.

It is believed that the many advantages of a grease container constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. A grease container of the class described comprising a cylinder for the reception of grease, said cylinder including a top on its upper end portion, a screw shaft extending rotatably through the top into the cylinder, an ejector threadedly mounted on the screw shaft for actuation thereby and operable in the cylinder, a sleeve mounted on the upper end portion of the screw shaft above the top, a pin securing the sleeve to the screw shaft and projecting outwardly from said sleeve, an operating handle for the screw shaft journalled for swinging movement on the end portions of the pin, an external flange on the lower end of the sleeve, and a packing mounted between said flange and the top for preventing leakage around the screw shaft where it passes through said top."

2. A grease dispensing container comprising a cylinder for the reception of grease, a bottom in one end of the cylinder, a' screw shaft rotatable in the cylinder, an ejector threadedly mounted on the screw shaft for actuation thereby and operable in the cylinder, said ejector having openings therein for the passage of the grease for permitting movement of the ejector through said grease, seats on the lower portions of the walls of the openings, headed elements mounted on said seats, check valves loosely mounted for swinging movement on said elements and engageable with the seats for closing the openings, and angular extensions integral with the valves and engageable with the seats for limiting the swinging movement of said valves toward open position.
